ASUS PRIME Z370-A II Intel Motherboard

With support for Intel 8th Generation processors in LGA 1151 packaging, the ASUS PRIME Z370-A II is engineered to provide true raw power. Take advantage of next-generation connectivity and speeds with NVMe M.2, USB 3.1 Gen2, DDR4 compatibility, and Intel Ethernet. 5X Protection III ensures excellent component longevity and reliability while Aura Sync RGB adds flair to your system. The intuitive ASUS UEFI BIOS makes tuning only clicks away. Just tune to get the best cooling and the highest performance.

Power Delivery Enhancements
DR. MOS

The Prime Z370-A II's CPU VRM utilizes Dr. MOS power stages that combine high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that Intel's latest processors demand.

ProCool power connector

Compared with traditional power inputs, ProCool sockets are built to tight specifications to ensure flush contact with the PSU power lines. This lowers impedance, which helps to prevent hotspots and connector failure.

Tune It Your Way
5-Way optimization

ASUS 5-Way Optimization makes your PC smart. One click takes care of complex tuning, dynamically optimizing essential aspects of the system to provide overclocking and cooling profiles that are tailored for your rig.

  • An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration.
  • Fans stay whisper-quiet with everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.
  • Stress test function helps optimize and overclock for CPU- or memory-centric workloads.
CPU performance boost

Unleash your PC's full performance with the ASUS AI Suite 3 utility. The TurboV Processing Unit (TPU) is the intelligence behind our automated system-tuning utility, offering the ability to fine-tune voltages, monitor system stats, and adjust overclock parameters for optimal performance.

All-round energy efficiency

With the Energy Processing Unit (EPU) you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.

Flexible cooling controls for air or liquid

With PRIME Z370-A II you have comprehensive control over fans, water pumps, and even all-in-one (AIO) coolers ? all via Fan Xpert 4 or our media-acclaimed UEFI. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click. There's also Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.

Precise digital power control

Digi+ delivers real-time control over voltage droop, switching frequency and power-efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.

App specific optimization for professionals and gamers

Whether you're a professional designer or hardcore gamer, you'll feel the benefit of the ASUS-exclusive Turbo App. This intuitive tool allows you to define CPU overclocking, apply fan profiles, prioritize network data and optimize audio settings at app level ? so your PRIME Z370-A II system is perfectly optimized for whatever you're doing.

Make your memory go faster

ASUS OptiMem preserves memory signal integrity by routing memory traces and vias to the optimal PCB layer, and our T-Topology layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements lead to more headroom for overclocking and improved stability, allowing memory speeds of DDR4-4000 and beyond with all slots populated.

OC Design – ASUS Pro Clock technology1

PRIME Z370-A II includes a dedicated base-clock (BCLK) generator that extends CPU and memory overclocking margins. This custom solution works in tandem with the TPU to enhance voltage and BCLK overclocking control, providing the flexibility to extract every ounce of performance from the Intel Core 8th Generation processors.

Cooler by design

PRIME Z370-A II features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

  • Each header can be set to monitor and react to three thermal sensors, and via Fan Xpert 4 you can even assign a sensor to monitor the temperature of supported ASUS graphics cards — for optimal cooling during GPU- or CPU-intensive workloads.
  • A dedicated PWM/DC header for self-contained water-cooling setups.
  • Each onboard header supports auto-detection of PWM or DC fans.
  • Includes three additional DC or PWM fan headers, plus three thermal-probe headers.
  • A dedicated integrated circuit protects each fan header from over-temperature and over-current.
ASUS Fan Holder

With the all-new ASUS Fan Holder increasing airflow your Prime Z370 Series motherboard's VRM area is simple. Just screw on a 40/50mm fan, mount the bracket on the heatsink, and hook the fan up to a header for a targeted cooling boost. With the Fan Holder and fan in place, VRM temperatures are reduced by up to 25°C — perfect for your overclocking adventures.

Media-acclaimed UEFI BIOS

The smoothest, slickest mouse-controllable graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, EZ and Advanced modes will help you quickly find your way, quickly and easily.

EZ Tuning Wizard

Quickly apply a CPU overclock to improve system performance, or configure a RAID array for faster data retrieval and backups.

Great motherboard 3/17/2020 11:39:49 PM

Pros: easy system setup and bios

Cons: has rgb but its it very visible at least in my case (nzxt h510i) but thought i say this bc i know some people are looking for that
my IO shield was kind hard to put in. I still don't have it on actually. I imagine i just got unlucky

Overall Review: bought this motherboard for my first ever pc build works fine never had any problems. Bios is very straight forward which i was grateful for as a first time user. was super easy to over clock my i7 8700k with no cofusion after minimal research
100% would recommend

good board, works as expected 2/11/2020 11:24:37 PM

Pros: Not too expensive
Lots of settings in BIOS

Cons: Not working out of the box
Lots of settings in BIOS

Overall Review: To any potential buyers: first thing - update BIOS.
If you do not
- expect computer freeze just after windows install disk started loading.
- memory would not be recognized, in my case it stopped seeing one out of 2x8GB

Another side note on Windows 10 installation.
I replaced motherboard, memory and cpu but kept hdd(all programs) and power supply. When I booted into windows 10 it told me that activation was lost. Let me ask you: how many of you keep windows 7 box once you upgraded to windows 10? If you can't find original box, google "ShowKeyPlus" program. It showed original windows 7 key so I was able to activate it again. I might have windows 7 box from original installation somewhere in garage.

Manufacturer Response:
Dear Terry A,

I'm sorry to hear you've encountered powering issues with your motherboard. When attempting to power your motherboard, were there any LED indicator flashing? Try unplugging the power adapter, then press and hold the power button for 20 seconds. If possible try swapping your PSU to debug for a defective unit? If the issues persist, feel free to contact me if you have any technical or general questions. You can reach me at cl-adrian@asus.com. Your case for reference is N200103036.

Thank you for choosing ASUS!

Best Regards,
Adrian
